Specification of Iietters Patent.

Patented Aug. 5, 1919.

Application filed December 20, 1918. Serial No. 267,615.

To all whom it may concern Be it known that we, LOUIS J. RIPICH and JOHNV. Hone, citizens of the United States. and residents of Cleveland,county of Guyahoga, and State of Ohio, and of East Cleveland, county ofCuyahoga, and State of Ohio, respectively, have jointly invented a newand useful Improvement in Safety Devices for Machinery, of which thefollowing is a specification, the principle of the invention beingherein explained and the best mode in which we have contemplatedapplying that principle, so as to distinguish it from other inventions.

The present improvements relate more particularly to the provision ofsuitable guard means for use in connection with power driven sewingmachines and the like, wherein there is belting underneath a table, bymeans of which power is communicated from a main drive shaft to asupplemental shaft and thence through a clutch (usually operated bymeans of a pedal) to the sewing machine, proper, or other operatingmecha' nism on top of the table. As is well known, women workers arelargely employed in the operation of machinery of this type and there isconstant danger that their skirts will be caught in the belting and thatin reaching beneath the table, their fingers may be similarly caught.The object of the present invention is to provide a simple andinexpensive design of guard for use in theconnection stated, one thatmay be attached to any stock type of table, and that will at the sametime be readily removable, should access be required to the drivingpulleys or belt.

To the accomplishment of the foregoing and related ends, said invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims, the annexed drawing and the followingdescription setting forth in detail certain mechanism embodying theinvention, such disclosed means constituting, however, but one ofvarious mechanical forms in which the principle of the invention may beused. in said annexed drawing Figure 1 is a transverse section through atable (specifically a sewing machine table of the type previouslyreferred to) showing our improved safety device or belt guard. partly inside elevation and partly in section; Fig.

2 is a front elevation of the same, the plane of the section of Fig. 1being indicated thereon by the line 11 and Fig. 3 is an enlargedsectional view of a detail.

As indicated above, the operating mechanism, e. 9., sewing machineproper, in machinery of the kindin hand is suported on a table 1., thereusually being a number of such machines on a table of indefinite length.Furthermore, the table is usually double, the operators sittingonopposite sides facing each other, witha depression or trough 2 betweenthe two parts of the table into which the finished work isdeposited. Ofcourse, only one side need be regarded for the purpose of the presentdescription.

The main driveor power shaft 3 extends longitudinally of the table beingsupported in suitable bearings l near the floor and having mountedthereon pulleys 5, onefor each machine on the table, from which thepoweris communicated through a belt 6 to a second pulley? mounted on acounter-shaft 8 or otherwise supported directly beneaththe of the table1, approximately midwayba tween its front and rear edges, is a mainguard member 11 which preferably, as illustrated, takes the formof awire screen of fairly close mesh, surrounded by a wire frame fromwhichone or more arms or fingers 12 project rearwardly into engagementwith the trough 2 or any corresponding depending part of the table. Itwill thus be seen that while member 11 may be swung outwardly, thesearms will prevent itbeing swung back beyond the vertical position inwhich it is shown in Fig. 1. In longitudinal extent, member 11 coversthe space in front of the individual operator, while it clears the floorbelow a sufficient amount to allow such floor to be cleaned withoutinterference with broom or mop.

Theone end of member 11f (the righthand end as shown in Fig. 2), extendsto a- H point adjacent to the belt 6 wherebyjthe two pulleys 5 and 7 areconnected, the upper pulley and the forward upper portion of such beltprojecting beyond the screen. In order to guard these against contactwith the operators clothes or fingers, a second guard member 15,likewise preferably made of "wire netting and of shallow basket form, ishung infroiit of'sa'idpulley and belt portion, being similarly swingablyattached at its upper end to hooks 16 o'n'the under side of the table,close to the front edge of the same; YAt, its lower'end, this last-'na1'ned member is formed with a hooked fork 17, or equivalent meansadapted to inter-engage theadjacent corner of the main member 11, '(seeig. Si1ch second member may 'bethus engaged, either before or after itis attached to the hooks 16, and is thus not only itself supportedproper position beneath the pulley 7 and forward portion of the belt,but atfthe same time serves to lock the main guard member in place, 2'.e.,

against being accidentally forwardly. From the foregoing description, itwill ae'ordingly be evident that our improved safety devicemaybevery'quickly and easily attached to any machineryv of the. general typereferred to, it being merely necessary tesupply-heoks properly spacedand located on the under side of the table, whereupbn the two guardmembers may be hung therefrom and secured together without the fuse of.any tools whatever.

1 W I v Similarlysaid members may be disengaged from each other andseparately raised or detached from the table without tools andon amoments no- 1t'ice.. The prbtection afiorded the operator of themachine, however, is as complete as c nts desired, more complete thanthat se- 35 whilethe cost ofmanufacturing the device cured by'iiianymore elaborateconstructions,
